Comparing the Centerlines of Cylinders in Measure X, 4 or 3

The Concentricity command in the GD&T menu compares the center lines of cylinders (one of them has to be a datum). However, if a 2D point to point dimension is desired then intersect both cylinders on the same plane.

- Measure 2 cylinders (that should share a center line)

- Measure a plane (or construct a parallel plane in between the 2 cylinders)

- Construct points where the cylinders intersect the plane. Construct Point < Line / Feature
